KHD T312 Gas Turbine

Another hand-crank started stationary engine the KHD T216. A small utilitarian power unit intended for use with pumps and generators. A simple but quality built engine with a power output of some 100HP. Compared to a diesel or petrol engine of the day it would have been much lighter in weight! Fuel consumption for a unit of this size is high compared to a reciprocating engine, it would typically use over 10 gallons per hour.

The magnificent but complex T312 is a single shaft APU designed for aircraft. One of a family of small but powerful power plants and the only one to be mass produced for fitment to the Tornado multi-role aircraft. An unusually laid out engine, the power take-off and reduction gearbox are at the back near the engine hot-section, a layout necessary when adopting a twin shaft layout but this unit is a single shaft design. The power take-off and gearbox could have been mounted at the front near the compressor a much cooler location! Perhaps the original design was going to be a twin shaft layout like a British Plessey Solent for example.

An intricate and complex engine originally fitted with a two stage compressor, later versions used just a single re-worked impeller type compressor. The oil system is used to provide an external hydraulic force and is consequently built for a greater capacity than what is required for the engine  and gearbox alone.

The T312 APU formed part of the Tornado Secondary Power System (SPS), when on the ground the aircraft systems could be driven by the APU independently of the main engines (RB199) and also used for starting them.
